Quizplus · Accepted Answer

Maria types 8 pages per hour. If she types one fewer page in an hour, she will be typing 7 pages per hour. This means she saves 1/8 of an hour for every page she doesn't type (since the rate is 8 pages per hour). Therefore, for not typing one page, she saves 1/8 of an hour. In that time, Maria can do:
$$\frac{1}{8} \cdot 12 = 1.5$$ 
loads of laundry. Hence, the answer is B: 1 1/2 loads.
